Poor Greta, I have a hard time watching her for more than 5 minutes at a time with her talking out of the side of her face. People need to be happy with the face God gave them and not mess with it.
She has always talked out of the side of her mouth. I don't think her plastic surgery affected that at all.
You are correct. Greta has always favored one side of her mouth over the other. I don't know why her producers haven't got her to kick this bad habit.
